'Lifted Up' in the Bible

And, as Moses lifted up the serpent in the desert, so must the Son of Man be lifted up;

So Jesus added: "When you have lifted up the Son of Man, then you will understand that I am what I am, and that I do nothing of myself, but that I say just what the Father has taught me.

And I, when I am lifted up from the earth, shall draw all men to myself."

"We," replied the people, "have learned from the Law that the 'Christ is to remain for ever'; how is it, then, that you say that the Son of Man must be 'lifted up' Who is this 'Son of Man'?"
